Application May 19, 1 932. Serial No. 612.326 1 Claim. (01. 129-13) Thisinvention relates to loose leaf binders and base member 1 and in thisinstance said postv provides a simplified form of binder having onlyprojects through a circular orifice in the base one binder post. Thisbinder is particularly member and has an annular flange 3 extendingadapted to be used in systems where a series of beyond the body of theorifice countersunk into 5 cards or sheets are used, the individualcards or the underneath portion of the base member and 60 sheetscontaining information about different acsecured by rivets 4.

A stack of sheets or cards 18 of any suitable size is provided in thebinder, and in the preferred form as shown in Figs. 1 and 2, the cardsare slightly smaller in dimension than the length and width of the topcovers'and are provided with an aperture slightly larger than the binderbar 2 and positioned between the cover. and the base member. To insertthe sheets the cover member is disengaged from the base and the binderpost inserted through the aperture of each sheet. Usually the sheets aretoo numerous to be accommodated by the binder post alone so theremainder are positioned with their apertures in alignment coaxiallyabove the binder post. tube member 9 is then inserted through the cardapertures and into the binder post and serves as a'retain'er forthe'sheets located above the top of the binder post. 1

After the entire binder has been assembled and the'binder locked withoutforcing the clamping bar down on the sheets, it is possible foranynumber of' the sheets to be rotated laterally around the binder post 2and tube 9, and to lock them in an'yldesired position by loosening the ilocking mechanism, pressing downwardly onthe clamping bar, and thentightening the locking mechanism, forexample, as shown in Figs. 1 and 2.

The adaptability of this binder in providing a multiplicity of possiblepositions for any number of its cards and. the ability to lock the cardsin any desired position is easily apparent and of substantial value andimportance. With this binder it is possible in a business where the stubpayment system is used to segregate, in the same binder, the sheetspertainingto different individuals, or firms, as to which the samecondition or status might exist and to group them in a vertical positionone .above' the other, without removing them from the binder, at anydesired point aroundthe axisflof the binder post. It is also possible tolock the sheets in any desired predetermined method of segregation sothat .they will not be accidentally disturbed or disarranged.

It will be understood that the base member 1 and clamping bar 5 form apair of binder members connected by a binding means or member formed bythe post 9 engaging binder post 2 and its associated locking mechanismso that the The her 1' and is in the form of a u-shaped rod, having thetwo legs 21 and 21 lying immediately adjacent and parallel to theopposite sides of the base member 1, when the prong structure is in ahorizontal or inoperative position. The prong structure is preferablyformed from a round rodand the portion of the structure connecting itstwo legs is provided in the central portion with two flat sides at rightangles to each other at 22 and 23, as shown in Fig. 3. The two sides 22and 23 are cut into the round rod leaving edges 24. A horizontal recess25 is also cut in the:base member 1, this recess intersectingat rightangles the transverse recess in the base member. A strip of spring metal26 is mounted in the longitudinal recess 25 and secured near one end bya rivet 27. The spring 26 overlies the fiat sides 22 and 23 of the prongstructure and is secured near its opposite end by a screw threaded bolt28, the bolt 28 extending through base member 1 and engaging in nut 29,countersunk in the underneathface of the base member. 5? Bolt 28 may betightened or loosened to increase or decrease the tension of the stripon the prong structure 20. The strip 26 is of sufficient width so thatits sides abut the edges 24 of: the prong structure, whereby the prongstructure is held against transversemovement. I I

The/prong structure 20 maybe rotated from the position shown in Fig. 5until its ends are in a vertical position, and the retaining strip bybearing upon the fiat surface 22, will retain it in such position. Theretaining strip will likewise retain the prong structure in itshorizontal position by bearing on the flat surface 23, after the prongstructure'has been moved to its horizontalposition. r

The prong structure, when in its vertical position, may be used toretain in position and in vertical alignment, any of the stack of sheetsor cards positioned between its two ends, even if the binder isnot'locked. If it is found desirable a similar prong structure may beprovided for the opposite'end of the-base member 1.

The invention claimed isi A loose leaf binder comprising a base memberhaving a hollow binder post, a clamping bar provided with a downwardlydepending hollow tube, said tube fitting into said binder post, lockingmeans in said tube for detachably locking said tubein thebinder post, aseries of sheets secured to and rotatable about said tube and binderpost and positioning prongs on said base member for retaining saidseries of sheets in one position on said base member when the lockingmeans are inoperative.
